This paper describes a solution for on-the-fly adapting the parameters of a video surveillance streams to system varying conditions, both in terms of data to be transmitted (number of streams to be sent) and of transmission conditions (quality of the available wireless link). This solution has been inserted in the system architecture of the EUREKA CELTIC(More)
Availability of modern, reliable and offering a wide range of services wireless communication systems is crucial for the effective operation of Public Protection and Disaster Relief (PPDR) agencies during the emergency situations. This paper presents the elements of the financial-economic analysis for acquiring and operating PPDR communication systems by(More)
In response to the growing demand in the public safety community for broadband communication systems, LTE is currently being adopted as the base technology for next generation public safety networks. In parallel, notable efforts are being made by the 3GPP to enhance the LTE standard in order to offer public safety oriented services. In the recent Release(More)
During this last decade, mesh networks have experienced strong growth due to their ability to provide an additional and complementary support for existing infrastructure communication systems. In such a network, routers are supposed to be fixed for short (e.g. public safety deployment) or long (e.g. network operator extension) period. This relative(More)
This paper presents high level design concepts for the control plane (C-plane) of the upcoming 5G networks, in the framework of Fixed-Mobile Convergence (FMC). This control plane is enabled by SDN and NFV technologies in order to offer a very flexible environment able to optimally deploy network infrastructure(s) that will cope with multiple service(More)
This paper presents an adaptive and controllable framework to optimize the transport of IP packets in military MANETs. The HBH (Hop-By-Hop) protocol that we propose uses a combination of hop-by-hop reliability and congestion mitigation mechanisms. Its major advantage is to run any standard IP application unmodified on top of the network. Moreover it is able(More)
In this paper, we propose a new approach for modeling and evaluating reliability of complex public safety network. Based on Bayesian network structure, we develop a general construction methodology for network representation and design. Using probability propagation techniques, the reliability of the system can be obtained in a straightforward manner. To(More)
